All-arthroscopic intramedullary nailing of 2- and 3-part proximal humeral fractures: a new arthroscopic technique and preliminary results

摘要

Purpose The most criticism of antegrade humeral nailing is the potentially deleterious effect on the shoulder function, which is caused by the trauma to the M. supraspinatus (SSP) at the nail insertion site. We describe a new technique of all-arthroscopical intramedullary nailing, which preserves the rotator cuff, and compare it with the conventional open procedure.
